java - 未知主机异常 Spring boot
问题描述
我的 Spring Boot 应用程序在除我的一个客户端之外的所有客户端上都能完美运行，这个环境的不同之处在于配置的代理。我生成了我的应用程序的 .war 文件并将其部署到 tomcat 9。
当应用程序尝试发帖时，它会发生
这是tomcat日志

这就是我实施我的帖子的方式。
public void sendListPayload(int count, List object, String controller) throws NoSuchAlgorithmException, IOException, SQLException {
String newSignature = "";
String answer = "";
Control type = Control.valueOf(controller);
String endereco = getaddress(type);
String payload = "";
RestTemplate restTemplate = new RestTemplate();
String url = endereco;
HttpHeaders headers;
payload = convertListToJson(object);
headers = newGetHeaders(payload);
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> entity = new HttpEntity<>(payload, headers);
restTemplate.getMessageConverters()
.add(0, new StringHttpMessageConverter(Charset.forName("UTF-8")));
try {
ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, entity, String.class);
logPayload(response.toString(),type.toString(),object.size());
} catch (HttpStatusCodeException e) {
if (config.getLogLevel().equals("DEBUG")){
log.debug(e.getMessage());
}else{
.. 日志信息（例如getMessage（））；}
}
}
我相信代理阻止了帖子的成功。
已经尝试在 catalina.bat 上添加代理设置
set "JAVA_OPTS =% JAVA_OPTS% -Dhttp.proxyHost = 192.168.0.254 -Dhttp.proxyPort = 3128"
但是没有效果
为了使我的代码能够在此代理环境中工作，我需要进行哪些更改？
